I started to notice a weird habit emerge in Mimi Lee. She was constantly scratching and licking her paws. My poor bedsheets were drenched in saliva, but Mimi Lee seems business as usual. Following an appointment with the vet, Mimi Lee was diagnosed with yeast dermatitis. Countless ear drops and ointments later, the stubborn yeast refused to give in. I needed to find out the root cause, so I did a little digging, unbeknownst to me, yeast infections are very common in dogs, especially in dogs with long ears.
